Touching the Void (2001)

The harrowing story of the 1985 ascent of Siula Grande in the Cordillera Huayhuash in the Peruvian Andes has to be seen to be believed. After climbers Joe Simpson and Simon Yates successfully reached the summit, Simpson broke his leg during the descent. Battling rugged weather, Yates thinks his partner is dead and cuts his rope, sending Simpson into a crevasse to fend for himself. The film, directed by Kevin Macdonald, mixes a reenactment of the journey with interviews with both men and has been called one of the greatest documentaries of all-time.
